What it is

An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.

Flow of Electrons

Many circuits have a switch so that they can be turned on and off. When the switch is off, it makes a gap in the circuit and the electrons are not able to flow around. When the switch is turned on, it closes the gap and the electricity is able to move and make the device work.

Closed and Open Curcuit

An open circuit does not allow a current to pass through. Wires in an open circuit do not connect with a bulb and battery, but in a closed circuit they do.
